FCM Sensors provide a low-cost flow verification option for PVC E-Series pumps. Installation on the suction side is simple, insulating the sensor from varying discharge parameters such as high or inconsistent pressures. Liquid pulled into the pump head during the suction stroke verifies pump operation, triggering a pulse output for each confirmed pump stroke. The FCM can be used to totalize chemical and sense when there is an no-flow condition (air-lock/loss of prime/dead head) when used with a controller or PLC.
